Key Stage 2
Meaning
Key Stage 3
Meaning
Lithium is a Group 1 element with an atomic number of 3.
About Lithium
- Lithium has the chemical formula Li.
- Lithium has 3 protons and 4 neutrons in its nucleus giving it an Atomic Number of 3 and an atomic mass of 7.
- Lithium is the least reactive Alkali Metal.
- Lithium is more reactive than Carbon on the reactivity series so it must be extracted from its ore using electrolysis.
- Lithium oxidises quickly in the presence of Oxygen so it must be stored in oil.
- Lithium reacts strongly with water to produce Hydrogen gas and Lithium Hydroxide.
- Lithium is a solid at room temperature.
- An atom of Lithium has only 1 electron in its outer shell.
- Lithium ions have lost an electron to become positively charged.

- Lithium is more reactive than Carbon on the reactivity series so it must be extracted from its ore using electrolysis.
- Lithium oxidises quickly in the presence of Oxygen so it must be stored in oil.
- Lithium reacts strongly with water to produce Hydrogen gas and Lithium Hydroxide.
- Lithium is a solid at standard temperature and pressure with a melting point of 180.50 °C.
- An atom of Lithium has only 1 electron in its outer shell.
- Lithium ions have lost an electron to become positively charged.
